Brian May revealed that he, Roger Taylor, and John Deacon all briefly quit Queen at certain points when recording album before changing their minds in a new interview. Queen Revealed Their ‘Last Moments’ With Freddie Mercury.
May indicated that Freddie Mercury was a bit more positive and confident in himself, so he never had any hesitation about his position in the band.
Classic Rock Magazine asked, “Being in Queen seemed to be a heavy burden for you at certain points. Did you actually enjoy it?”
It’s tough, because you’re always struggling to make your own identity work within the identity of the group. If you’re in a situation and you feel like your voice isn’t being heard, it’s very negative – it motivates you to be mean and dogmatic and uncompromising and resentful. We all felt like that at various times. I know Roger felt it, John did as well. Freddie… I don’t know. Freddie was always a cup-half-full person. A cup-completely-full person, really.
But we all left the band at various points in various album sessions. I remember being in Munich, when we were doing The Game, I think, walking around the English Garden, thinking: ‘This is over. I’m never going to do this again.’ And then you get back in there and you put your gloves back on.”
